No, not 'Very well, Your Excellency', but simply 'Your Excellency'! I told you to watch your tone, Colonel! I also trust you will not be offended if I suggest you make a slight bow and at the same time incline your body forward, so as to indicate respect and also, as it were, readiness to dash off on an errand for him. I've been in the company of generals myself, so I know what I'm talking about ... So 'Your Excellency'.
